There appears to be confusion about what client sites will look
like. I have had the <a
href="https://www.hamwan.org/t/tiki-index.php?page=Client+Node+Routing&structure=HamWAN">Client
Node Routing</a> page up for a while, but it did not contain a
clear pictographic view, nor a thorough textual description. I've
now spent a little time to draw up a clear graphical representation
of what to expect at your site. Just hit up that page to see.<br>
<br>
Your local router and wireless access point are staying, as is your
Internet modem. The newly added HamWAN microwave modem + router
will simply plug into the LAN side of your network.<br>
<br>
From a routing perspective, the HamWAN modem will announce routes to
your main router via RIP <i>most likely</i> (see below). These are
subnets which are accessible via the microwave network and the
packets for those subnets should be sent to the microwave modem.
Default gateway <i>should</i> (see below) stay as your main ISP.<br>
<br>
If you have received subnet routing services from HamWAN (ie: you
have your own subnet which is announced into the rest of the HamWAN
network) then you'll configure your LAN devices with your subnet's
IPs.<br>
<br>
The open problems in this design are:<br>
<br>
1) Asymmetric reply traffic when requests come into your HamWAN
subnet from Internet IPs. The reply packets will attempt to leave
via your ISP since it's your default gateway. We may have to do
some policy routing on the main router to mitigate this, or multinet
any network devices which want to talk out both networks. To be
engineered.<br>
<br>
2) DNS queries need to work for at least the HamWAN.net domain
despite a total Internet failure (of both your local ISP and
HamWAN's Internet links). DNS queries for regular Internet domains
should be undisturbed during normal operation.<br>
<br>
HamWAN should not request any control over user routers beyond the
HamWAN modem + router device. On the HamWAN modem + router device,
users need to be free to define their own firewall rules and set
other settings which do not conflict with HamWAN access policy.<br>
